Weird bug?

[Edi]

If you have the turn file, post ot as an attachment so IW can take a look at it.

Maybe the Pan went beserk* and killed the sacred satue while the rest of your army was fleeing?

(*by casting a spell,wearing a beserker pelt or equpping an amulet of the lycanthrope)

Nope the statue was not killable by what i had there. And i watched until all my troops had fled off the map.

After 40 turns, all units auto-retreat. After 60 turns, all units that are still on the battlefield are being killed. Maybe this happened here - the statue is immovable, after all, any maybe that Pan somehow didn't get to the back soon enough.
